  • THE COMPONENTS OF TOTAL HEAD

    Pump energy consumption is directly proportional to the flow rate, the pump head, the efficiency of the pump and the motor. In cooling applications, the energy provided to the pump itself and transferred to the water has to be compensated by the chillers. Therefore, pumping energy needs to be paid twice in cooling: at the pump and at the chiller.
